It's in the shiny piece. The other one with the spring under the head.

No, it's the throttle rocker arm with the screw and the spring. It's the one up towards the top closest to the manifold.

It's the shiny piece at the top in the photo Glen posted. It's on the shaft that goes through the top of the carb in between the two bolts that hold it onto the manifold.

Hi,
If you are talking about the idle speed adjustment screw, it is behind the carburetor, when the carburetor is installed, on the engine side of the carb, at the top of the carb, on the movable throttle shaft where the governor rod connects on.
The end of the screw with the screwdriver slot is forward when the engine is a low speed.
It is visible in the pic I posted of the engine side of the carb.

Maybe it is gone, could be why you can't find it.

The other screw that goes into the top of the carb casting, is the idle mixture adjustment screw. :)

I took the fuel sediment bowl off to inspect the screen and screwed up the home made gasket. I have a new screen and gasket coming, but I now have to remove the hood...and of course I just fueled up. If I have to remove it, does the fuel sediment assembly simply unscrew from the tank?

You don't have to remove the hood to replace the screen and gasket.

Hi,
Yes, the gas strainer screws into the gas tank.
It is easier to get to it if you move the Touch Control arms to the rear position before beginning work on the strainer. Put some gas in the carburetor somehow through the gas line, run the engine, and lower the arms if you need to. Maybe you won't need to take the hood off. :)
